Abstract
Neurorehabilitation focuses on restoring function in patients with central and peripheral nervous system disorders, yet effective therapeutic options remain scarce. This study introduces a novel nanocopolymer, CaCO3-PAAm-GDCA, synthesized through reversible addition-fragmentation chain transfer polymerization of glycodeoxycholic acid, acrylamide, and CaCO3. This nanocopolymer exhibits a sharp and reversible insoluble-to-soluble transition in water at a temperature related to its upper critical solution temperature (UCST), which can be finely adjusted to a practical range around 37 °C, suitable for biomedical applications. The addition of β-cyclodextrin (β-CD) modulates this transition temperature by forming host-guest complexes, further enhancing the copolymer’s adaptability. When loaded with compound 1, the resulting CaCO3-PAAm-GDCA@1 significantly promoted the proliferation of damaged neuronal HT22 cells and inhibited ferroptosis through the modulation of Nrf2 and GPX4 pathways. This study provides a strong foundation for the development of neuroprotective drugs, highlighting the potential of tailored nanocopolymers in advanced neurorehabilitation therapies.
